modem speaker ... and those modem noises

English Hardware
1

I’m having a problem I haven’t had before. When I uncheck the box to have
the modem speaker on in the modem configuration under Yast (kde3.5,
opensuse 11), the setting doesn’t save. The modem makes a lot of those
awful noises at connection.
My girlfriend asked about the mechanism behind the data transfer that
results in an audible, albeit unpleasant, sound. I’m clueless on that one.
Could anyone enlighten us or possible tell us how to avoid having those
sounds to ponder over?
Thanks,
-Tom (and Abby)

Hi
It’s your modem and the remote one negotiating the connection. You can
use the AT command L0 (Modem AT Command Set) in
your init string to turn it off.

Thanks for the tip. That list is great. I’ve added “L0” to the “INIT2” line
of /etc/sysconfig/network/ifcfg-modem0 as follows, but I’m still waking the
dead with every connection. I’m assuming this is the correct place to
add “L0”.
Thanks again.

Tom;

ATM1 ( see INIT8 above) sets the speaker on until carrier detect, try ATM0
which should turn the speaker off. Since you send M1 after L0 it may reset
the volume. Google “Hays commands” to find the various AT commands. I
confess that it’s been over ten years since I actually setup a dial up
connection.

Garn!
That was it. I looked up all the others in the list and overlooked M1. Thank
you both very much!
